Go for new job or stay at old job?

I work for Gala Bingo and i enjoy the job but the money isn't the best i only pick up about �185 a week. I applied for a job months ago to work in a new warehouse that was opening up in my town and today they rang me and offered me a position. I don't know what to do the job i have been offered is more money but most people are saying they treat you bad in there so i could leave for the money and wish i had stayed at my job or i could stay at my job and then i'll always think what if. What do i do? Please help
